How to Understand & use adjective agreements & the word bien

Pierre-Benoit Heriaud explains the various meanings of the French word bien. Firstly, there is one obvious meaning the common "good" or "acceptable". However, one can also use it in sentences such as "Il fait bien froid" to present the current status of the weather as being excessive in one way. In this case, it can easily be replaced with the adverb "vraiment", not losing any bit in meaning. Lastly, the word "embete" might also be a trap in that it usually means annoyed, but can be associated with different situations.
